OPTICAL DISC RECORDING PULSE CONTROL METHOD, AND CONTROL DEVICE AND OPTICAL DISC DEVICE EMPLOYED THEREIN

摘要

There are problems that recording degradation happens, and an error occurs in reproduction unless appropriate recording pulse conditions are determined. A recording pulse controlling method according to the present invention is a recording pulse controlling method for adjusting recording pulses for recording information on a writable optical disc, which includes a mark length adjustment step and a mark position adjustment step. The mark length adjustment step is a step for adjusting a recording mark length adjustment parameter, and the recording mark length adjustment parameter is adjusted to have a value for forming a recording mark having a length closest to a predetermined recording mark length. The mark position adjustment step is a step for adjusting a recording mark position adjustment parameter after the mark length adjustment step, and the recording mark position adjustment parameter is adjusted to have a value for forming a recording mark at a position closest to a predetermined recording mark position.
